Title (EN) IMPROVED PRINTED CIRCUIT WHICH CAN DETECT ACCIDENTAL HEATING
(FR) CIRCUIT IMPRIME PERFECTIONNE, ADAPTE A LA DETECTION D'UN ECHAUFFEMENT ACCIDENTEL
Abstract: front page image
(EN)The invention relates to a printed circuit (10) comprising a support (12) which insulates under the normal operating conditions of the printed circuit (10). The printed circuit (10) bears at least component (14) which can accidentally generate the unwanted heating of a sensitive area (Z) of the support (12). For said purpose, the printed circuit (10) also comprises means for detecting the heating of the sensitive area (Z). The aforementioned detection means comprise means (26) that are sensitive to an increase in the conductivity of the support (12) with temperature.
(FR)L'invention concerne un circuit imprimé (10) comprenant un support (12), isolant dans les conditions normales de fonctionnement du circuit imprimé (10). Le circuit imprimé (10) porte au moins un composant (14) susceptible de provoquer accidentellement un échauffement indésirable d'une zone sensible (Z) du support (12). A cet effet, le circuit imprimé (10) comporte encore des moyens de détection de l’échauffement de la zone sensible (Z). Les moyens de détection comprennent des moyens (26) sensibles à l'élévation de la conductivité du support (12) avec la température.
